T 274 Mining Truck

Proven design. New format.

Liebherr T 274. The new 305 tonne payload truck.

Liebherr is extending its product offerings with the T 274, a class-leading 305 t / 336 tons haul truck. This new truck bridges the gap between the highly successful T 284 (363 t / 400 tons) and the T 264 (240 t / 265 tons).

Operating the T 274 with other Liebherr Mining products provides the opportunity to achieve the greatest productivity, while minimising operating costs.

The T 274 follows the same base design as the T 284, benefitting from its decades of field experience. Operators and technicians can expect to experience first-class comfort and safety while driving and servicing this truck. A wide range of options are available, not only providing maximum productivity even in the harshest conditions, but also catering to the evolving requirements of customers and mine sites.

This new 305 tonne truck can be fitted with the Liebherr Trolley Assist System, a significant step towards zero emission mining.

Powerful, strong, and reliable

Designed and adapted from years of experience in mining truck development, the T 274 is a true 305 tonne machine that provides fast cycle times, higher production rates, low fuel consumption, and a low cost per tonne.

Unmatched performance

The Liebherr T 274 is powered by the most powerful engine in its class at 3,650 hp, and the efficient Liebherr Litronic Plus AC Drive system. With the advanced hydraulic design and fast cycle times, the T 274 moves more material in less time.

Designed with safety in mind, the T 274 is equipped with 4,500 kW / 6,035 HP dynamic braking power to operate efficiently on downhill hauls.

Class leading payload

This new addition to Liebherr's mining product range offers a truck with the largest payload capacity in its class, moving more tonnes each hauling cycle.

Pairing the Liebherr T 274 with the Liebherr R 9800 hydraulic excavator provides the customer with highly versatile and productive fleet. The fast swing times of the R 9800 will load the T 274 with 4 bucket passes ensuring quick loading times that lead to high production rates of both the truck and excavator.

High speed on grade

Speed on grade is a major contributor to fast cycle times. The Liebherr Litronic Plus AC Drive System improves cycle time efficiency by providing continuous uphill speed, differing from traditional mechanical drive trucks that require shifting of gears.

User-centric design

Liebherr is committed to designing mining trucks that operators want to drive. The ergonomic design of the T 274 cab creates a safe, comfortable, and productive environment for operators. The cab provides maximum visibility utilising tinted safety glass windows, and is certified for roll-over and falling-object protection. The integrated HVAC system provides comfort in all temperature extremes. All Liebherr trucks offer at least two safety exit routes from the cab to the ground.

Liebherr mining trucks are equipped with ladders and platforms that allow easy machine access. The ground level maintenance areas provide safe and efficient service access.

Double A-arm suspension

Double A-arm suspension keeps optimal ground contact of the tyre within the whole suspension stroke, reducing the tread and wear with optimised camber and toe angle.

These properties of the front suspension system deliver superior comfort, safety, and handling for the T 274 operators improving the ride quality and reducing overall body vibration exposure.

Active intelligent control systems

The Liebherr active intelligent control systems provide safety for the operator:

Four wheel speed sensing to optimise traction performance
Slip-slide control to reduce torque on wheels which rotate faster and provide on-demand torque requirements
Traction control in which torque is automatically adjusted to the rear wheels to maximise traction when cornering accelerating from a standstill, or traveling on wet or icy roads
Anti-roll back operable in forward and reverse
Operator adjustable dynamic braking speed limit control for downhill operations
Configurable speed limits for loaded and unloaded states
Configurable speed inhibiters for truck overload, reverse, and dump body raise

Ground level service access

Easy access to check brake component wear
Service door on axle box for inspections
Central service station with quick disconnects
Sight glasses on most of the major components
Driver side mounted battery disconnect box
Easy filters and manifolds access

Versatile for all applications

The T 274 has been designed to operate in the harshest conditions while meeting the demands of an ever-evolving mining environment. With its well know engineering expertise, Liebherr is able to offer various application-specific solutions to support our specific customers' needs around the world.

Special environment packages

Liebherr offers an array of specific solutions for customers working in extreme environments. These packages guarantee that the T 274 will be fit for any working conditions.

The High Altitude package enables the trucks to be operated at altitudes between 3,500 m / 11,500 ft and 5,000 m / 16,400 ft above the sea level.
The Arctic package enables the T 274 to be operated in extreme cold weather conditions. Specific solutions have been created to protect the components and help customers operate machinery in temperatures as low as -40°C/F.
Sound Attenuation packages reduce truck noise emissions drastically by using a low speed fan, enclosed engine bay, and custom mufflers. This ultra-quiet option gives customers the flexibility to run operations day or night, without disturbing nearby residential areas.

Trolley Assist System

The Liebherr Trolley Assist System is an effective first step on the road to zero emission mine sites of the future. Utilising an overhead pantograph to connect the electric-drive system to the electrical network, the Trolley Assist System offers:

Increased truck fleet productivity, or reduction in fleet size while maintaining yearly production, when compared with standard trucks
Significant reduction of diesel fuel consumption
Reduction of carbon footprint by decreasing the truck fleet CO2 emissions

Liebherr delivers proven field experience with 38 T 284 units fitted with the Trolley Assist System already in operation on two different sites.

Multiple engine options

Liebherr partners with leading providers of high-horsepower diesel engines, incorporating Tier 4 Final certified engine technology, to provide customers with a choice of efficient and reliable engine solutions. Tier 4 solutions are designed to reduce emissions and satisfy local requirements established by the EPA for all new mining equipment.

This practical consideration is an example of Liebherr’s commitment to customer satisfaction, environmental sustainability, and continuous improvement.
